New to Android - Some Help Please?

I have switched from always having an iPhone to the world of Android. The fact being able to customize so much more than what iOS offered made me switch. I have a few questions.

1- I downloaded the faecbook app and I have lightflow. I have hidden the facebook application and I was wondering is there any way that I can get the notification light to blink blue and NO other notification like on the status bar. Just the notification light thats it. On the facebook app i went into settings and there was no option to do so. I enabled the LED to blink blue when i recieve a facebook notification but however due to it being hidden I think that is why it does not work. Any Suggestions?

2- Is there any possible way for me to switch between music libraries? Like suppose there as app that lets me do that lets call it "XYZ". So I open XYZ and press a profile and then my music library changes to the songs that i put in that profile and doesent show the other songs in my other profile. Its kinda hard to display or simpler terms is there any way for me to switch between music libraries or hide songs in music library?

3- Can i use quick shortcuts to open an app? Like lets say i double tap the status bar and that lets me open up and app? Is there any way to do this.

Thanks and I am on Galaxy s4 Jellybean 4.2.2

Welcome to the forums and Android! Hope you are liking the device.

1. I have an app called Light Manager. It allows you to do many of the things you are talking about. I have completely different colors from stock telling me what is happening. Free on Play, but you may have to pay the developer to do the option you would like. (I am not sure, what I needed done is free and I don't use Facebook.)

2. You could try a second music app, but I have found many of the music apps are unable to play certain types of music files. Poweramp can play all types of files but aside from the 2 week trial period it is a paid only app. I do like it though. Great app. I don't know if you can manipulate the device to do what you would like. You can stick with stock, and create folders. Stock app should be able to read folders ok (again, I don't know. all my music is lumped together and I could care less about organizing my library)

3. That doesn't really work on Android. COUNTER QUESTION: with this question, what exactly did you have in mind?
